To @ZZ whom it may concern.-

Be it known that I, CHARLES FRANKLIN with the adjustable and detachable planing or cutting bits i, it being intended to provide,

OVERMYER, a citizen of the United States, rei .in connection with the cutter-head, a series of siding at Upper Sandusky, in the county of Wyandot and State of Ohio, have invented certain new and useful Improvements in Cutter-Heads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cutter-heads; and the object in View is to provide a cutter-head of novel construction which will enable the head to be applied to ashaft at any point, either outside of the bearings of said shaft or between the bearings thereof, without the necessity of removing the shaft from its bearings. 4

The improved cutter-head is divided'on a central diametrical line, and the two sections of the cutter-head are so constructed and related to each other that the sections may be separated in order to enable them to be applied to a shaft, and when applied they are capable of being clamped or fastened together and at the same time andv by the same opera tion upon the shaft.`

The detailed objects and advantages of the Ainvention will be fully pointed out in the f course of the subjoined description. The invention consists in a cutter-head involving certain novel features and details of construction and arrangement of parts, as,

hereinafter fully described, illustratedin the drawings, and incorporated in the claims.

1 In the accompanying drawings, Figure 1 is a perspective view of the improved cutterhead applied. Fig. 2 is a section taken through the cutter-head transversely of the shaft on which the cutter-head :is mounted. Fig. is a plan View of the cutter-head, showing the manner of adjusting the cutter-head sections4 usual adjustable scoring or cutting bits 3 and interchangeable bits for effecting t-he different operations to which the head is adapted.

-Both sections of the cutter-head are provided with abutting flanges, those on the section 1 being numbered 5 and 6 and those on the section i. being numbered 7 and S. These flanges meet on a line diainetrical to the shaft on which the cutter-head is mounted. The flange G is provided with a chamfered face or edge 9, and the 'flange 8 of the section 2 has at its outeriedge an undercut bead 10, the undercutting of the bead forming a lip 11, which f overhangs the ange 6 and which has an inclined or chamfered under surface which corresponds to and cooperates with the cham fered face 9 of the flange 6, thus producing a cam action as the two sections of the cutterhead are brought together, which action tends to force the two sections of the cutter-head closely together and upon and in hard fricwith a bevel-faced rib 12, and the vflange 5 has its outer edge correspondingly beveled to cooperate therewith, so that as the flange 5 is forced toward the flange 7 the coperating beveled faces (indicated at 13 and 14) will crowd the flange 6 and its chamfered face 9 againstthe bead 10, with the effect hereinabove noted.

Openings 15 are formed through the flange 7 and rib 12 at points unequally distant from the ends of the cutter-head, and clampingbolts 16 are passed through said openin gs and provided with nuts 17. Each bolt is alsoprovided with a laterally-proj ectin g head 18, said head projecting only from one side of the bolt, so that it may extend over and outside of the flange 5 of the section 1 or by turning the bolt be moved out of engagement with the dange 5, so as to allow the two sections of the cutter-head to be separated. The bearing-surfaces ofthe bolt-heads are oblique or inclined with relation to the line of division between the sections of the head, and the outer surfaces of the flanges upon which the heads rest are correspondingly inclined or oblique, so that the accidental turning of the bolt-heads is prevented. The object in locating the bolts posite ends of the cutter-head is to allow for adjusting one section of the cutter-head rela tively to and longitudinally upon the other section and at the same time enabling both bolts to be used as clamping means for the two sections. In order to enable the sections to be accurately adjusted for giving the desired width of cut, the flange 5 and the bevelfaced rib 12 are graduated, as indicated at 19. By so adjusting the cutter-head sections any desired width of cut may be obtained, varying from the width of one of the cutting-bits to the combined width of the bits.

By means of the construction above described it will be seen that not only can the cutter-head sections be adjusted relatively to and upon each other for giving the desired width of cut, but at the same time the sections inay be clamped securely and firmly upon the shaft, and in this operation it is not necessary to remove the shaft from its bearings nor to slip the cutter-head from the end of the shaft; but the cutter-head sections may be separated and applied to the shaft at any point whatever, thus saving time and avoiding the necessity of accurately adjusting the bearings of the shaft every time a new cutter-head is applied to or removed therefrom.l The application of the cutterhead to its shaft and the relative adjustment of the cutter-head sections are facilitated and expedited by constructing the sections so that they interlock at one side of the axis of the cutter-head and are clamped at the opposite side by means ot' the bolts.

The improvements hereinabove described are designed to be applied and used in connection with any kind of cutter-head whatever-wabble-saw, shear-cut, or straight-cut. The cutter-head as a Whole is especially designed for shaping up canopy-top frames, body-sills, and b ars in the manufacture of carriages, as well as for window, door, and cistern frames, and, in fact, in any place where a cutter-head is desired. The cutterhead may also be used for square turning, such as balusters, newelposts, porch-columns, dre.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

l. .A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the shaft, and adjustable relatively to each other in a direction parallel to said axis.

2. The combination with a shaft, of a cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division, and provided with abutting flanges having interlocking shoulders.

3. A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division, and provided with abutting flanges having interlocking shoulders.

4t. A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division and provided with abutting flanges having cooperating beveled shoulders, and clamping means for said flanges, producing a wedging action of the shoulders.

5. A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division, abutting flanges on the sections, one of which has a chamfered face and theA other an undercut bead arranged to lap the chamfered face, and clamping means common to both sections.

6. A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division, abutting flanges on the sections formed to interlock on one side of the axis and having cooperating beveled shoulders at the other side of the axis, and clamping means for fastening the sections together and upon a shaft.

7. A cutter-head comprising two sections divided on a line diametrical to the axis of the head and separable transversely of the line of division, abutting flanges on the sections, one of which has a chamfered face and the other an undercut bead comprising a chamfered lip which overhangs and coper ates with said chamfered face, and clamping means for holding the sections together and upon a shaft.

8. A cutter-head comprising two sections separable on a line diametrical to the axis of the head, abutting flanges on the sections, and a clamping-bolt passing through the flange of one section and having a laterally-projecting head which extends over and bears upon the flange of the other section.

9. A cutter-head comprising two sections separable on a line diametrical to the axis of the head, abutting flanges on the sections, and clamping-bolts passing through the flange of one section and having heads which engage the flange of the othersection, said bolts being located at unequaldistances from the ends of the iianges.

10. A cutter-head comprising two sections divided on a line diametrical to the axis of the head, abutting iianges on the sections, and clamping-bolts passing through the flanges of one section and having heads which engage the flanges of the other section, the bearingsurfaces of the bolt-heads being oblique or inclined with relation to the line of division, the flange upon which the boltlheads bear having a correspondingly-inclined coperating surface.

In testimony whereof I affix my signature in presence of two witnesses.
